So are you thinking about a service that generates thread dumps (or tweaking the existing one), with configuration options to control where the dumps go? With hooks to inject the service into other interested services, e.g. HAPartition? HAPartition would then decide whether an event (e.g. a timeout on an RPC) justifies calling into the thread dump service. In the case of an RPC timeout, only the caller knows it happened.
